HEADS Site is a CAD-driven software specifically designed for a variety of applications in the planning and execution of irrigation projects, including the design of canals, bunds, and dykes, as well as facilitating de-siltation dredging operations. This innovative tool can accurately calculate the storage capacity of water in reservoirs located at dams or barrages by monitoring fluctuations in water levels, employing a digital terrain model and contours derived from ground elevation data captured through the Shuttle Radar Topography Mission (SRTM) via Global Mapper, all without requiring any on-site surveys. Additionally, the software incorporates slope stability analysis utilizing Bishop's method, efficiently managing diverse survey data, digital terrain models (DTM), triangulation, contours, and satellite imagery. It also allows for the conversion of coordinates from TM (Survey) to UTM (GPS), enabling seamless communication with Google Earth for optimal planning of bypass and green field alignments. Moreover, it facilitates the online acquisition of ground elevation data from the SRTM, eliminating the need for traditional topographic surveys and enhancing the geometric design of alignments for irrigation projects. This comprehensive approach not only streamlines project planning but also maximizes accuracy and efficiency in irrigation development efforts.
